Unioned layers of coal resource calculation in the Kaiparowits Plateau study area, southern Utah (kai*fing)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2021-06-15T00:00:00Z
These are shapefiles and polygon coverages that contain numerous attributes of information on coal in the Calico and A-sequences of the Upper Cretaceous Straight Cliffs Formation in the Kaiparowits Plateau study area in southern Utah. These layers were derived from a "union" process of combining numerous polygon coverages using the Environmental Systems Research Institute, Inc. (ESRI) Arc/Info UNION command, and finally calculating coal tonnage in INFO. Net coal thickness values are from 209 data points and represent all coal beds that are more than 1 foot thick. The outside polygon defines the base of the coal-bearing Calico and A-sequences east of 112 degrees of longitude. The northern boundary is delineated by the Paunsaugunt fault and basal outcrops of volcanic rocks of Tertiary age.
